摘要: Disclosed embodiments include a method for synchronizing a cryptosystem. In one embodiment, the method uses existing control data that is transmitted as part of a connection establishment process in a wireless communication system. In one embodiment, messages that are normally sent between a base station and a remote unit during the setup of both originating and terminating calls are parsed to detect a particular control message that indicates the start of telephony data transmission. Detection of this message indicates a point at which encryption/decryption can begin, and is used to synchronize the cryptosystem. Synchronizing a cryptosystem involves generating an RC4 state space in a keyed-autokey (“KEK”) encryption system. In one embodiment, Lower Medium Access Channel (“LMAC”) messages are used according to a wireless communication protocol. This is convenient because the LMAC messages are passed through the same Associated Control Channel (“ACC”) processing that encrypts and decrypts the telephony data.

摘要: A method of calibrating antenna-position detection associated with a radar system, the radar system including a first gimbal and a first angle sensor configured to detect an angular position of the first gimbal, includes mounting a second angle sensor to the first gimbal configured to detect an angular position of the first gimbal. The first gimbal is rotated through each angular position of a set of the angular positions. A first set of data is generated with the first angle sensor that characterizes a detected angular position of the first gimbal. A second set of data is generated with the second angle sensor that characterizes a detected angular position of the first gimbal. A third data set is determined comprising differences, between the first and second data sets, in detected angular position at each first-gimbal angular position. The third data set is stored in a memory device.
